Application filed June 5, 1913. Serial No. 771,799.

TouZZ whom it may concern Be it known that T, WALTER S. ADAMs, a citizenof the United States, and a resident of the city of Philadelphia, countyof Philadelphia, and State of Pennsylvania, have invented a new anduseful Improvement in Car-Trucks, of which the following is aspecification.

The object of my invention is to provide a'suitable truck for storagebattery cars, which truck will be light, durable, ellicient andsatisfactory under all the conditions of service. This object isaccomplished by my invention, one embodiment of which is hereinafter setforth.

For a more particular description of my invention, reference is to behad to the accompanying drawings, forming a part hereof, in which:

Figure 1 is a side elevation of a portion of my improved truck. Fig.2 isan inverted plan view of a spring cap. Fig. 3 is a sectional view, takenon the line 33 of Fig. 2, looking in the direction of the arrows. Fig. 4is a plan view of a portion of the structure shown in Fig. 1. Fig. 5 isa sectional view taken on the line 55 of Fig. 1, looking in thedirection of the arrows. Fig 6 is a sectional view, taken on the line 66of Fig. 4, looking in the direction of the arrows. Fig. 7 is a sectionalview, taken on the line 77, of Fig. 1, looking in the direction of thearrows. Fig. 8 is a plan view of an axle box. Fig. 9 is partly asectional view, taken on the line 9-9 of Fig. 8, looking in thedirection of the arrows, and partly a side elevation. Fig. 10 is asectional view, taken on the line 10-40 of Fig. 9, looking in thedirection of the arrows. Figs. 11 and 12 show a bracket for a springpost with a seat for a spring, the bracket being used to hold the lowerend of the post, Fig. 12 being taken on the line- 1212 of Fig. 11,looking in the direction of the arrows. Figs. 13 and 14 show a bracketfor supporting a car body from one end to the elliptical spring, Fig. 14being taken on the line 1414 of Fig. 13, looking in the direction of thearrows. Fig. 15 is a sectional view taken on the line 1515 of Fig. 8,looking in the direction of the arrows.

Throughout the various views of the drawings, similar referencecharacters designate similar parts.

The invention herein disclosed may be applied to a truck 1 which may beeither connected directly to a car body, where extreme lightness isdesired, or to top chords, not shown, which may be attached to a carbody. In either case this truck 1 is provided with the usual wheels 2,axle 3, brake mechanism 4 and electric motor supports 5 all of which maybe of the conventional form. The axles 3 are journaled in axle boxes 6which have novel features. These axles 3 bear directly on suitableroller or other bearings, not shown, which may be of the conventionalform. These bearings are secured to the axle boxes 6 by means of boltsor cap-screws which pass into suitable perforations, 7, which arelocated in the usual manner.

The axle boxes 6 have suitable side webs 8 and 9 united by a crossing 10and spring seats 11, 12, 13 and 14, the spring seat 11 be ing for asemi-elliptic spring and located at one end of the webs 8 and 9. Thespring seats 12 and 13 are located symmetrically on each side of thecrossing 10 and the spring seat 14 is located at the other end of thewebs 8 and 9 and is suitable for coiled spring. 7

The spring seats 12 and 13 each carry suitable coiled springs 15, (seeFig. 5,) which is surmounted by a suitable cap 16 from which hangs asuitable bolt or spring post 17, which passes through a suitableperforation in the seat 12 or 13 and also through a coiled spring 18between the seat 12 or 13 and a seat 19 on a clamp 19 and between thisclamp and a tie-bar 20, the

clamp and tie-bar being held together by.

means of suitable bolts 21. By means of the nut 22 at the lower end ofthe spring post 17 the springs 15 and 18 are put under suitable tensionso that the axle box 6 will ride sub stantially true at all timesregardless of the difference in action between'leaf and coiled springson the application of the brakes. The tie-bar 20 unites the two axles 6on the same side of the truck. This tie bar 20, in conjunction with theposts 17 and springs 18 serves to prevent tilting of the axle box underthe normal conditions of service. This tie bar constitutes'an equalizingbar.

The spring seat 14 carries a suitable coiled spring 23, is surmounted bya suitable cap 24, and this cap rests against a top chord or the carbody and is secured to one or the other, according to which structure isused.

In the structure shown this cap is secured to the car body. This cap 24is provided with a suitable cup 25 and central perforation 26 so astoreceive a suitable spring post '27 which passes therethrough, and alsothe-conventional manner, that is the band 30 of this spring rests onsaid seat and suitable U bolts -31 secure the spring '29 in place. Ihefree ends of the spring'29 carry suitable seats 32 in which rest swinglinks 33 which also engage suitable brackets 34: which are connected, asshown, or otherwise, as desired, so that the car body is carried by thecaps 24 andth'e brackets 34 and is always spring supported while socarried in a manner which permits a limited transverse or verticalmovement. The parts are preferably shaped as shown in Fig. 7, so as tofacilitate this result.

Below the seat 11 and fixed to the axle box 6 by suitable bolts 35 issecured the crossing 36 from which are carried both the brake rigging 4and the motor support 5.

. When a truck frame is made as above set forth the batteries may becarried by the tiebar 20 or otherwise, as desired. The bars may alsocarry the motor should such a construction be desired; In any event,when the truck is in use and the car is loaded so that the springs 23and 29 are compressed the axle '3 can shift to a slight extent as abovestated because of the flexible connections of the springs to the car'body. It is also true that the axle boxes 6 will be held in properrelation and in their normal condition with- V out regard to thedifference in action between the springs 23 and 29 because of thetension on the springs 15 and 18 as above set forth.

lVhile I have shown and described one embodiment of my invention, it isobvious that it is not restricted thereto, but is broad enough to coverall structures that come within the scope of the annexed claims.
